Cheapest Mac to run GLM-4.6

355B parameters (32B active) · quality index 45 · coding 68 · every Apple Silicon Mac ever sold, compared. It is a mixture-of-experts model: all 355B parameters must sit in memory, but only 32B compute per token, which is why it is faster than dense models of similar size.

The cheapest Mac that runs GLM-4.6 comfortably is a used Mac Studio M3 Ultra 32c/80c 512GB (2025) at about $7,457 EST. on the used market — running Q6_K quantization at roughly 16 tok/s with up to 200K tokens of context.
